Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------
The factors of 5 are 1 and 5. 12 = 2 x 5 + 2 x 1, therefore: 4x2 +12x +5 = (2x + 1)(2x + 5)
You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.You must add 36 to complete the square on the left hand side.
x2 + 12x - 11 = x2 + 12x + (12/2)2 - (12/2)2 - 11 = (x + 6)2 - 47
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
8x squared
9
x^2 + 12x = 5 x^2 + 12x + __ = 5 + __ x^2 + 12x + 36 = 5 + 36 (The 36 I got from taking half of 12 and then squaring that number (which is 6).) (x + 6)^2 = 41 x + 6 = (the square root of 41) x = (the square root of 41) - 6. Hope that helped :)
It is x^2 + 12x or x(x + 12).
4x2+12x = 4x(x+3) when factored
12x and then the squared. (the little two)
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
(3x - y+ 2)(3x + y + 2)
x2 - 12x + 36 = (x - 6)2
9x2...I guess that means 9x squared ? The problem: 9x(squared)+12x+4 Here's the answer: (3x+2)(3x+2) or even more simplified: (3x+2) squared
x - 2
6(x + 1)(x + 1)
